Physical Sciences Grade 12 | VirtualX MasterClass – Course Module 1 provides students with an in-depth exploration of Mechanics, a fundamental topic in physics. This module focuses on the principles of motion, energy, and forces, preparing students for higher-level problem-solving and real-world applications.

Through interactive lessons, hands-on problem-solving, practical examples, and assessments, students will strengthen their conceptual understanding of:

• Momentum and impulse, including Newton’s Second Law
• The motion of objects under gravity through vertical projectile motion
• The work-energy theorem and power calculations

By the end of this module, learners will have developed critical analytical and problem-solving skills that will enable them to confidently tackle physics problems related to mechanics, motion, energy, and forces. These concepts lay a strong foundation for university-level studies in science, engineering, and technology.

This course consists of three structured lessons, each covering key mechanics principles.

Lesson 1: Momentum and Impulse

  • Understanding momentum and its dependence on mass and velocity
  • Applying Newton’s Second Law in terms of momentum
  • Exploring the conservation of momentum in elastic and inelastic collisions
  • Real-world applications of impulse, such as airbags, crumple zones, and sports

Lesson 2: Vertical Projectile Motion in 1D

  • Graphical representation of motion: displacement, velocity, and acceleration vs. time
  • Understanding the effect of gravity on objects in free fall and upward motion
  • Solving equations of motion to calculate time of flight, maximum height, and velocity

Lesson 3: Work, Energy, and Power

  • Applying the work-energy theorem to real-world motion scenarios
  • Conservation of mechanical energy, including the role of non-conservative forces (friction, air resistance)
  • Power calculations and their applications in physics and engineering

Each lesson includes interactive activities, problem-solving exercises, quizzes, and assessments to ensure deep comprehension and engagement.
